Bulk Density of the Lunar Regolith at the Chang'E‐3 Landing Site as Estimated From Lunar Penetrating Radar

Earth and Space Science, 2020
Bulk density of the lunar regolith is a key factor affecting its geophysical and geotechnical properties. In this study, a new method for estimating the bulk density of the lunar regolith is developed based on the geometric characteristic (i.e ...

SOYBEAN COMPRESSIBILITY AND BULK DENSITY

Transactions of the ASAE, 2000
The objective of this project was to study the influence of surcharge pressure and moisture content on the compressive behavior and bulk density of soybeans. Three varieties were selected with varying dimensions and shapes. Moisture contents of 10.5, 15.0, and 20% were tested at nine surcharge pressures in the range from 0 to 82.8 kPa.

Bulk modulus-density systematics [PDF]

Journal of Geophysical Research, 1969
The elastic constants of crystals show a general tendency to increase as the mean molar volume 〈V〉 = 〈M〉/ρ decreases. The role of other factors, such as cation radius, crystal field effects, and anion-cation coordination, can now be discussed with available elastic constant data.

Modeling the Impact of Rhizosphere Bulk Density and Mucilage Gradients on Root Water Uptake

Frontiers in Agronomy, 2021
In models of water flow in soil and roots, differences in the soil hydraulic properties of the rhizosphere and the bulk soil are usually neglected. There is, however, strong experimental evidence that rhizosphere and bulk soil hydraulic properties differ

Physical properties of kernels from modern maize hybrids used in Croatia [PDF]

Journal of Central European Agriculture, 2020
The physical properties of maize are a result of kernel structure, they indicate chemical properties of the kernel, and hence, its nutritive value. This research aimed to explore the physical traits of kernels of 80 commercial maize hybrids from nine ...

Soil compaction caused by 450C Timber Jack wheeled skidder (Shefarood forest, northern Iran)

Journal of Forest Science, 2007
In forest harvesting operations usually after using skidding machinery (skidders), traces of soil damage in the form of soil compaction and wheel and logs ruts can be seen in the forest soil. Soil bulk density, which represents soil compaction, decreases

Rational Use of Herbal Products in Pediatric Patients Treated With Anticancer Drugs in the European Union

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.

The density of superconductivity in the bulk regime [PDF]

Indiana University Mathematics Journal, 2018
In the asymptotic limit of a large Ginzburg-Landau parameter, we give a new asymptotic formula for the $L^2$-norm of the Ginzburg-Landau order parameter. The formula is valid in the bulk regime where the intensity of the applied magnetic field is of the same order as the Ginzburg-Landau parameter and strictly below the second critical field.
